What is the molarity of 0.8 moles of KCL in 2L of solution

The molarity is 0,4M

Explanation:

The molartity is moles of compound (in this case KCl) in 1 liter of solution :

2 L0,8 moles KCl

1 Lx= (1L x0,8 moles KCl)/2L= 0,4 moles KCl--> 0,4M

  The number of balloons varies directly with the number of tables. The two variables are directly proportional. The relationship of balloons to tables is the ratio 5:1, where 5 is the constant of variation. Use the equation y = kx, where k is the constant of variation resulting in the equation y = 5x.
